Hi Bob. I myself who has no web (code) or HTML5 experience was impressed with the HTML STACKER plug-in as it gave me a number of "fancy" HTML5 techniques, such as gravity (physics), image slide shows, drag &amp; drop and a whole number of features I could use.

Searching the web I have not found much that resembles HTML STACKER.

Are there any you could point out to us? (I really like Adobe Edge, but it's far from what HTML STACKER can offer in terms of simplicity).

You're preaching to the choir. Besides adding video and audio tags there's nothing overly fascinating about HTML5. CSS3 on the other hand is amazing and I should point out, works quite nicely plain old ordinary HTML.
